SM
then U will be +3.6 V max. The frequency increases by a factor of 10. If the
smallest displayed number is N = 30 (lower numbers are possible, but
inaccurate) and the highest No = 3000, then U will be -4 V max. The frequency
changes by a factor of 100.
The frequency change is linear as a function of the voltage U and has the same
value in all ranges.
When the switch OFFSET
is depressed, a DC voltage can be superimposed
on the output signal. The maximum offset voltage with open output is ± 5 V.
: Input signal to the counter is given to EXT IN
BNC terminal.
The minimum applied signal is 50 mVrms and maximum applicable signal is
150 Vrms.
: In normal mode counter is auto triggered. When TRIG
switch is
pressed, instrument can be triggered externally by adjusting LEVEL
knob.
When instrument is triggered trigger LED is ON.
: The input signal to frequency counter can be attenuated 10
times by pressing 1:10 Switch .
: When switched ON the instrument
works as a function generator. By pressing FC
switch the instrument
functions as a Frequency Counter
.
The
5076 is equipped with triple power supply isolated from each other. It
has 5 V/ 1 A, 2 x 15 V/ 1 A. The power supply is short circuit protected and any
overload is indicated by litting LED indicator.
The 5 V power supply output can be adjusted from 4.5 to 5.5 V, similarly 15 V
power supply output is adjustable from 14.5 V to 15.5 V.
For applications where positive and negative voltages are required with a
common ground, e.g. in operational amplifiers power supply requirement 15 V
power supplies can be used. Negative of one 15 V power supply may be
connected with negative of another power supply, will ve - GND - ve.
